Python set copy() Method: Shallow Copy Examples

set.copy() returns a shallow copy of a set. The returned set is a different container, so adding or removing elements from the copy does not change the original set.

This is useful when you want to experiment with mutable set operations while preserving the original collection.

Set order: sets are unordered. Whenever an example prints a set, the displayed element order can differ between runs or Python environments.

my_set={'a','b','c','d','e'}
my_set2=my_set.copy()
print(my_set2)

Output is here

{'d', 'a', 'b', 'c', 'e'}

Modifying a Copy

Changes to copied_set don’t affect original_set.

original_set = {1, 2, 3}
copied_set = original_set.copy()
copied_set.add(4)
print(copied_set)      # Output: {1, 2, 3, 4}
print(original_set)    # Output: {1, 2, 3}

Using a Copy for Set Operations

The copy lets you perform operations without altering the original.

set1 = {'apple', 'banana'}
set2 = set1.copy()
set2.remove('banana')
print(set2)   # Output: {'apple'}
